Association between perioperative glucocorticoids and cancer metastasis and survival in patients undergoing radical cystectomy for urothelial carcinoma of the bladder: A single-center retrospective study.	PURPOSE: Perioperative glucocorticoids have the potential to increase the risk of tumor metastasis. However, the relationship between perioperative glucocorticoids and oncologic outcomes remains controversial. The present study was undertaken to evaluate the association of perioperative glucocorticoids with clinicopathologic outcomes following radical cystectomy (RC). MATERIALS AND METHODS: We screened and included 185 patients who underwent radical surgery for bladder cancer in our center between 2009 and 2018. The Kaplan-Meier method was applied, and a log-rank test was used to estimate differences in metastasis-free survival (MFS) and overall survival (OS) between the groups. Multivariate Cox proportional hazards regression models were used to analyze any association of glucocorticoids with clinical outcomes. RESULTS: A total of 76 (41.1%) patients received perioperative glucocorticoids. Median postoperative follow-up was 2.0 years. Kaplan-Meier survival curve indicated that the glucocorticoids group was significantly associated with increased distant MFS (p=0.008) but not with OS. In the multivariate analysis, no significant differences were observed for MFS between the groups. Interestingly, when the variable of blood transfusion was excluded from the multivariate analysis model, we found that patients receiving glucocorticoids were independently associated with worse MFS (hazard ratio, 1.790; p=0.030). Furthermore, the partial correlation analysis showed a significant positive correlation between perioperative glucocorticoids and blood transfusion (r=0.604, p<0.001). In the nontransfusion subgroup, propensity score matching showed that patients receiving glucocorticoids had a higher risk of distant metastasis. CONCLUSIONS: Perioperative glucocorticoids were associated with a higher rate of distant metastasis in patients undergoing RC for bladder cancer.	bladder
Intraoperative upper urinary tract cytology examination is a risk factor of upper urinary tract recurrence in patients with non-muscle-invasive bladder cancer.	OBJECTIVES: To evaluate the impact of intraoperative upper urinary tract (UUT) cytology examination in patients with non-muscle-invasive bladder cancer (NMIBC) who had undergone transurethral resection of bladder tumor (TURBT). MATERIALS AND METHODS: We retrospectively evaluated 414 patients with NMIBC who had undergone transurethral resection of bladder tumor between November 1993 and April 2019. Patients with simultaneous UUT urothelial carcinoma (UC) detected via computed tomography were excluded. Patients were divided into 2 groups: those who had undergone intraoperative bilateral UUT cytology examination via retrograde catheterization (study group) and those who had not (control group). We evaluated the utility of intraoperative UUT cytology examination, comparing surgical outcomes and perioperative complications between the 2 groups. In addition, we evaluated the impact of UUT cytology examination on UUT recurrence using background-adjusted multivariate analysis. RESULTS: We obtained 292 UUT urine samples from 146 patients with a median age of 72 years. Of 292 UUT urine samples, 11 (3.7%) were positive and 3 were finally diagnosed as UUT UC. Positive predictive value and false positive rate were 18% and 3.1%, respectively. Operative time for the study group was significantly longer than for the control group. Rate of perioperative complications were not significantly different between the 2 groups. However, in background-adjusted multivariate analysis, intraoperative UUT cytology examination was associated with significantly shorter UUT recurrence-free survival. CONCLUSION: Intraoperative UUT cytology examination may not be recommended as a result of low positive predictive value due to contamination and UUT recurrence risk in patients with NMIBC.	bladder
TIM-3 and TIGIT are possible immune checkpoint targets in patients with bladder cancer.	The resurgence of immunotherapy as an effective anticancer strategy has been coupled with more mature understandings of the underlying immune pathways and the development of novel immune checkpoint targets. The clinical development of antibodies first directed against cytotoxic T-lymphocyte-associated antigen 4, and later against program death 1, achieved durable disease control in a subset of patients across a large number of tumor types. Previous work demonstrates that targeting the programmed death 1 pathway alone does not result in complete restoration of T cell function and in some cancers, targeting this axis does not restore T cell function at all, suggesting a need to identify other molecules and inhibitory pathways that are involved in T cell exhaustion. In a comprehensive immune profiling study of patients with bladder cancer, we demonstrate T-cell immunoglobulin domain and mucin domain-containing molecule and T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain as possible targets as perhaps monotherapy or in combination with other immune checkpoint inhibitors.	bladder
Current status of genetic urinary biomarkers for surveillance of non-muscle invasive bladder cancer: a systematic review.	BACKGROUND: Genetic biomarkers are a promising and growing field in the management of bladder cancer in all stages. The aim of this paper is to understand the role of genetic urinary biomarkers in the follow up of patients with non muscle invasive bladder cancer where there is increasing evidence that they can play a role in avoiding invasive techniques. METHODS: Following PRISMA criteria, we have performed a systematic review. The search yielded 164 unique articles, of which 21 articles were included involving a total of 7261 patients. Sixteen of the articles were DNA based biomarkers, analyzing different methylations, microsatellite aberrations and gene mutations. Five articles studied the role of RNA based biomarkers, based on measuring levels of different combinations of mRNA. QUADAS2 critical evaluation of each paper has been reported. RESULTS: There are not randomized control trials comparing any biomarker with the gold standard follow-up, and the level of evidence is 2B in almost all the studies. Negative predictive value varies between 55 and 98.5%, being superior in RNA based biomarkers. CONCLUSIONS: Although cystoscopy and cytology are the gold standard for non muscle invasive bladder cancer surveillance, genetic urinary biomarkers are a promising tool to avoid invasive explorations to the patients with a safe profile of similar sensitivity and negative predictive value. The accuracy that genetic biomarkers can offer should be taken into account to modify the paradigm of surveillance in non muscle invasive bladder cancer patients, especially in high-risk ones where many invasive explorations are recommended and biomarkers experiment better results.	bladder
Upregulation of lncRNA plasmacytoma variant translocation 1 predicts poor prognosis in patients with muscle-invasive bladder cancer.	LncRNA plasmacytoma variant translocation 1 (PVT1) has been recognized as an oncogenic lncRNA, which participates in the migration and invasion of many kinds of cancer cells and the development of cancers. In the present study, we explored its clinical significance and prognostic value in muscle invasive bladder cancer (MIBC).A total of 98 MIBC patients' samples were collected, who had undergone radical cystectomy from the March 2013 to December 2018. The associations between PVT1 expression and clinical data were calculated using the Chi-test. Overall survival curves were determined by the Kaplan-Meier technique and contrasted via log-rank test. We utilized univariate and multivariate Cox proportional hazard models to examine the HR and 95% CI.The expression levels of PVT1 were significantly higher in MIBC tissues than that in normal bladder tissues (P < .001). PVT1 expression was significantly correlated with tumor grade (P = .009), margin (P = .002), T stage (P = .02), and lymph node metastasis (P < .001). MIBC patients with high PVT1 expression level had shorter overall survival than those with low PVT1 expression level (log-rank test, P = .004). Multivariate Cox regression analysis showed that PVT1 expression level (HR = 2.381, 95% CI: 1.821-7.012, P = .014) was an independent factor in predicting the overall survival of MIBC patients.In summary, increased PVT1 expression in MIBC patients is correlated with a higher MIBC stage and is significantly associated with poor prognosis for MIBC patients, which may provide new insights into new therapeutic strategy and postoperative intervention against bladder cancer.	bladder
Screening of hub genes and prediction of putative drugs in arsenic-related bladder carcinoma: An in silico study.	BACKGROUND: Evidence showed that inorganic arsenic (iAs) can trigger malignant transformation in cells with complex mechanisms. Thus, we aimed to investigate the possible molecules, pathways and therapeutic drugs for iAs-induced bladder cancer (BC) by using bioinformatics approaches. METHODS: Microarray-based data were analyzed to screen the differentially expressed genes (DEGs) between iAs-related BC cells and controls. Then, the roles of DEGs were annotated and the hub genes were screened out by protein-protein interaction network. The key genes were further selected from the hub genes through an assessment of the prognostic values. Afterward, potential drugs were predicted by using CMAP analysis. RESULTS: Analysis of a dataset (GSE90023) generated 21 upregulated and 47 downregulated DEGs, which were enriched in various signaling pathways. Among the DEGs, four hub genes including WNT7B, SFRP1, DNAJB2, and ATF3, were identified as the key genes because they might predict poor prognosis in BC patients. Lastly, Cantharidin was predicted to be a potential drug reversing iAs-induced malignant transformation in urinary epithelium cells. CONCLUSION: The present study found several hub genes involved in iAs-induced malignant transformation in urinary epithelium cells, and predicted several small agents for iAs toxicity prevention or therapy.	bladder
Comparison of the Immunotherapy Response Evaluation Criteria in Solid Tumours (iRECIST) with RECIST for capturing treatment response of patients with metastatic urothelial carcinoma treated with pembrolizumab.	OBJECTIVE: To evaluate the clinical usefulness of Immunotherapy Response Evaluation Criteria in Solid Tumours (iRECIST) in patients with metastatic urothelial carcinoma (UC) treated with pembrolizumab. The iRECIST is designed to accurately capture the tumour response treated with immunotherapy. PATIENTS AND METHODS: We conducted a multicentre retrospective study evaluating the clinical utility of iRECIST in 91 patients with metastatic UC treated with second-line pembrolizumab. The objective response (OR) and time to progression (TTP) in accordance with both iRECIST and RECIST version 1.1 were compared with overall survival (OS) and risk of all-cause mortality, and analysed using log-rank and multivariable Cox regression models, respectively. Predictive performance of the criteria was studied using Harrell's concordance index (c-index). The clinical usefulness of each criterion was compared using decision curve analysis. RESULTS: Of 57 patients with progressive disease per RECIST, a considerable number of patients were reclassified to immune stable disease (six, 10.5%), immune partial response (two, 3.5%), and immune complete response (two, 3.5%) per iRECIST. Multivariable Cox regression models showed that both OR (hazard ratio [HR] 0.10, 95% confidence interval [CI] 0.03-0.35; P = 0.001) and TTP (HR 0.59, 95% CI 0.46-0.77; P < 0.001) per iRECIST were significantly associated with all-cause mortality. Furthermore, iRECIST had a significant, increased predictability of OS compared with RECIST (OR, c-index: 0.70, increase: 0.04, P = 0.046; TTP, c-index: 0.88, increase: 0.07, P = 0.039). On decision curve analysis, iRECIST presented better net benefit gains than did RECIST. CONCLUSIONS: Compared with RECIST, iRECIST could more accurately predict OS of patients with metastatic UC treated with pembrolizumab. The iRECIST has the potential to be a new standard for tumour response evaluation of these patients.	bladder
The natural course of urinalysis after urinary diversion.	OBJECTIVE: To evaluate the impact of urinary diversion on regular features of urinalysis and to screen for risk factors of infection-related complications. METHODS: We conducted a retrospective, single-centre study of 429 patients who underwent open radical cystectomy. Patients were followed for 12 months and data of the complete urinalyses were analysed at three pre-defined time points. RESULTS: Two weeks after surgery, dipstick testing with positive reactions for leukocyte esterase and haemoglobin were confirmed in 80.7% and 80% after ileal conduit (IC) and orthotopic ileal neobladder (NB), respectively. Every patient was positive for these parameters 12 months after surgery. Correspondingly, the microscopic examination detected leukocytes (84% vs. 85.4%), erythrocytes (82.8% vs. 83.8%) and bacteria (94.3% vs. 96.8%) following IC and NB reconstruction. After 12 months, all parameters were positive irrespective of the type of urinary diversion. Two weeks after surgery positive urine cultures were obtained in more than 50% of cases after IC (52.5%) and NB (60.5%) (p > 0.05). All urine cultures were positive after 12 months with significantly more poly-microbial results found after NB (81.3%) compared with IC (67.2%) (p = 0.018). In univariate and multivariate logistic regression analysis the presence of hydronephrosis was independently associated with the occurrence of infectious complications (OR 4.2; CI 95% 1.525-11.569; p = 0.006). CONCLUSION: A positive urinalysis is a common finding after urinary diversion. Hydronephrosis is a serious risk factor with respect to infection-related complications. The simple fact of a positive urinalysis does not warrant antimicrobial treatment.	bladder
Targeting Stat3 signaling impairs the progression of bladder cancer in a mouse model.	Bladder cancer is the fourth most commonly diagnosed malignancy in men worldwide and has one of the highest recurrence rates of all cancers. This cancer type is unique because chronic inflammation caused by Schistosoma haematobium can cause bladder cancer, while inflammation induced by Bacillus Calmette Guerin is the therapeutic cornerstone for this cancer type. Activation of proinflammatory IL-6/Stat3 axis promotes the development of different cancers by acting on cancer cells as well as by modulating cancer microenvironment. Using a genetic and pharmacological approach in a mouse model, we demonstrated the importance of IL-6 and Stat3 signaling in bladder cancer. Our findings show that pharmacological inhibition of Stat3 with WP1066 effectively delays progression and invasiveness of bladder cancer in N-butyl-N-(4-hydroxybutyl) nitrosamine-induced mouse model. Moreover, either IL-6 blockade or Stat3 inhibition sensitized bladder cancer to anti-PD-L1 immune therapy. Taken together, our study demonstrates an important role of IL-6/Stat3 signaling in bladder cancer and creates a rationale for testing the therapeutic potential of Stat3 inhibitors in human MIBC both alone or in combination with anti-PD-L1 and anti-IL-6 therapy.	bladder
Enhanced CDR1as Promotes the Development of Bladder Urothelial Carcinoma.	BACKGROUND: The current study aimed to evaluate the expression of circular RNA (circRNA) CDR1as in bladder urothelial carcinoma and adjacent normal tissues, thereby laying the foundation for the research of bladder urothelial carcinoma. METHODS: The level of CDR1as was evaluated in the tissues of bladder urothelial carcinoma patients. ROC analysis was carried out to explore the possible diagnostic value of CDR1as. RESULTS: In the current study, we showed novel data that the expression of CDR1as in bladder urothelial carcinoma tissues was significantly higher than that in adjacent tissues. Furthermore, the expression of CDR1as was significantly higher in non-muscle invasive bladder cancer (NMIBC) and high-grade cancer tissues than in muscle invasive bladder cancer (MIBC) and low-grade cancer tissues. In patients with lymph node metastasis, the expres-sion of CDR1as was also significantly higher. Moreover, the expression of CDR1as was higher in high-stage, high-grade bladder urothelial carcinoma than in low-stage and low-grade cancer tissues. Real time PCR analysis showed that there was no difference in the expression of CDR1as among the patients according to the grouping of gender (male vs. female), age (≤ 65 years vs. > 65 years), tumor size (≤ 3 cm vs. > 3 cm), and lymphatic invasion (LVI). CONCLUSIONS: The current study for the first time showed upregulation of CDR1as may be involved in the development and progression of bladder urothelial carcinoma.	bladder
Low compliance to guidelines in nonmuscle-invasive bladder carcinoma: A systematic review.	PURPOSE: This systematic review assessed compliance to guidelines for the management of nonmuscle-invasive bladder carcinoma (NMIBC). METHODS: The PUBMED, Web of Science, Cochrane Library, and Scopus databases were searched in November 2019 in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement. RESULTS: Fifteen studies incorporating a collective total of 10,575 NMIBC patients were eligible for inclusion in this systematic review. We found that the rates of compliance were 53.0% with a single immediate intravesical instillation in patients with presumed low or intermediate risk, 37.1% with intravesical bacillus Calmette-Guerin or chemotherapy in those with intermediate risk, 43.4% with performance of a second transurethral resection in high-risk patients, 32.5% with administration of adjuvant intravesical bacillus Calmette-Guerin in high-risk patients, 36.1% with radical cystectomy in highest-risk patients, and 82.2% with cystoscopy for follow-up. CONCLUSIONS: Compliance with NMIBC guidelines remains low. Better guideline education and understanding holds the key to achieving high compliance. Strategies to improve guideline compliance at the physician level are urgently required.	bladder
Effect of low-energy shock wave therapy on intravesical epirubicin delivery in a rat model of bladder cancer.	OBJECTIVES: To study the efficacy of low-energy shock wave therapy (LESW) on enhancing intravesical epirubicin (EPI) delivery in a rat model of bladder cancer (BCa). MATERIALS AND METHODS: A total of 100 female Fischer rats were randomly allocated into five groups: control; BCa; LESW; EPI; and EPI plus LESW. After BCa induction by N-butyl-N-(4-hydroxybutyl)nitrosamine, EPI (0.6 mg/0.3 mL of EPI diluted in 0.3 mL saline) or saline (0.6 mL) was administered and retained in the bladders for 1 h with or without LESW treatment (300 pulses at 0.12 mJ/mm(2) ). This was repeated weekly for 6 weeks. Survival was then calculated, rats were weighed and their bladders were harvested for bladder/body ratio estimation, histopathological examination, p(53) immunostaining, miR-210, hypoxia-inducible factor (HIF)-1α, tumour necrosis factor (TNF)-α and interleukin (IL)-6 relative gene expression and fluorescence spectrophotometric drug quantification. Heart and blood samples were also collected for assessment of the safety profile and toxicity. RESULTS: The EPI plus LESW group had significantly lower mortality rates, loss of body weight and bladder/body ratio. Histopathological results in terms of grossly visible bladder lesions, mucosal thickness, dysplasia formation and tumour invasion were significantly better in the combined treatment group. The EPI plus LESW group also had statistically significant lower expression levels of p(53) , miR-210, HIF-1α, TNF-α and IL-6. LESW increased urothelial concentration of EPI by 5.7-fold (P < 0.001). No laboratory variable exceeded the reference ranges in any of the groups. There was an improvement of the indicators of EPI-induced cardiomyopathy in terms of congestion, hyalinization and microvesicular steatosis of cardiomyocytes (P = 0.068, 0.003 and 0.046, respectively) in the EPI plus LESW group. CONCLUSIONS: The combined use of intravesical EPI and LESW results in less BCa invasion and less dysplasia formation, as LESW increases urothelial permeability of EPI and enhances its delivery into tumour tissues, without subsequent toxicity.	bladder
Electronic reporting of patient-reported outcomes in a fragile and comorbid population during cancer therapy - a feasibility study.	BACKGROUND: Electronic collection of patient-reported outcomes (ePROs) is becoming widespread in health care, but the implementation into routine cancer care during therapy remains to be seen. Especially, little is known of the use and success of electronic reporting during active cancer treatment in fragile and comorbid patients. The aim of this study was to test the feasibility of ePRO and its incorporation into routine cancer care, measured by physician compliance, for a fragile and comorbid bladder cancer (BC) population receiving chemo- or immunotherapy. METHODS: All BC patients initiating treatment for locally advanced or metastatic bladder cancer at Rigshospitalet or Herlev Hospital, Denmark, were approached during an 8 month period. Exclusion criteria were patients not speaking Danish or not being signed up for electronic communication with health authorities. Enrolled patients were prompted to complete weekly ePROs from home. Patients completed the European Organisation for Research and Treatment of Cancer's general quality of life questionnaire, QLQ-C30, and the module for muscle-invasive bladder cancer QLQ-BLM30, the Hospital Anxiety and Depression Scale, HADS, and selected items from the Patient Reported-Outcomes version of the Common Terminology Criteria of Adverse Events (PRO-CTCAE), in total 158 questions weekly. If failing to report when prompted, patients were sent two e-mail reminders. Patients were informed that the physician would have an overview of the reported ePROs at their following clinical visits. Physicians were at all clinical visits informed to look at the ePROs in a software solution separate from the medical records. Physicians were logged to check their compliance to the task. No continuous surveillance of ePROs was established. RESULTS: Of 91 patients screened for enrolment, 19 patients (21%) were not found eligible for standard treatment, eight patients (9%) were not signed up for electronic communication with the health authorities and nine patients (10%) declined participation. Another six patients did not meet other inclusion criteria. In total 49 BC patients were enrolled, 29 initiating chemotherapy and 20 initiating immunotherapy. A total of 466 electronic questionnaires were completed. The overall adherence of the patients to complete ePROs was at an expected level for an elderly cancer population (75%) and remained above 70% until the 6th cycle of treatment. The physician' compliance was in contrast low (0-52%) throughout the course of treatment. CONCLUSIONS: Electronic reporting of PROs is feasible in a fragile and comorbid population of patients during routine active cancer treatment. Despite clear implementation strategies the physician compliance remained low throughout the study proving the need for further implementation strategies.	bladder
